  public void Restore(string Filepath)
        {
            try
            {
                if(con.State == ConnectionState.Closed)
                {
                    con.Open();
                }
                SqlCommand cmd1 = new SqlCommand("ALTER DATABASE [" + Database + "] SET SINGLE_USER WITH ROLLBACK IMMEDIATE ", con);
                cmd1.ExecuteNonQuery();
                SqlCommand cmd2 = new SqlCommand("USE MASTER RESTORE DATABASE [" + Database + "] FROM DISK='" + Filepath + "' WITH REPLACE", con);
                cmd2.ExecuteNonQuery();
                SqlCommand cmd3 = new SqlCommand("ALTER DATABASE [" + Database + "] SET MULTI_USER", con);
                cmd3.ExecuteNonQuery();
                con.Close();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
            con.Close();
        }
